Processing Endpoint SAP Active/Standby Status Bits
The advertised admin forwarding status of active/standby reflects the status of the local LAG SAP
in MC-LAG application. If the SAP is not part of a MC-LAG instance, the forwarding status of
active is always advertised.
When the SAP in endpoint "X" is part of a MC-LAG instance, a node must send T-LDP
forwarding status bit of "SAP active/standby" over all "Y" endpoint spoke SDPs, except the ICB
spoke SDP, whenever this status changes. The status bit sent over the ICB is always zero (active
by default).
When the SAP in endpoint "X" is not part of a MC-LAG instance, then the forwarding status sent
over all "Y" endpoint spoke SDP's should always be set to zero (active by default).
